Hi everyone, first post here and like many first posts it's because I'm after a little help.

This weekend my 98 1.8T died, I needed a car and a friend of a friends brother had a 2003 A3 1.6 for sale, so I bought it (I do miss that turbo and engine remap!).

Anyway there was a mysterious beep when I started the car after about 30 seconds, finally figured out it was bluetooth looking for a phone (a Nokia CK-7W is what appears on my phone). So I paired up my iPhone and it all seemed to work, I could make calls and the audio came through my cars speakers.

As I knew nothing about this bluetooth setup I went online to find out more about it and discovered that there is supposed to be some kind of external module with a button and volume control. In my car there is nothing, I've looked under seats and all around the dash but I cannot see this external module. This wouldn't be such a huge issue but for the fact that I have to re-pair my phone everytime I get in the car and reading around it appears to be because there is already a phone paired to the system and this is the prefered phone it keeps in memory or something. To reset the system I need this control apparently.

Failing that I wondered if there was some kind of reset on the actual Nokia Ck-7W module, but I have no idea where this would be, I assume it's behind the stereo?

So my question is, does anyone know where I could find the actual bluetooth module and if I can reset the system using it, or do I need the external button device to do that?

Thanks for any help/guidance or pointers to resources anyone has, my Google-Foo has been seriously lacking for this.
